rust/tests/codegen/cffi, branch 1.84.1

more `asm!` -> `naked_asm!` in tests

2024-10-06T16:12:25+00:00

Add `-Zlint-llvm-ir`

2024-08-29T10:12:31+00:00

Use the aligned size for alloca at args when the pass mode is cast.

2024-07-01T22:33:35+00:00

The `load` and `store` instructions in LLVM access the aligned size.

Remove c_unwind from tests and fix tests

2024-06-19T12:54:55+00:00

Run rustfmt on `tests/codegen/`.

Except for `simd-intrinsic/`, which has a lot of files containing multiple types like `u8x64` which really are better when hand-formatted. There is a surprising amount of two-space indenting in this directory. Non-trivial changes: - `rustfmt::skip` needed in `debug-column.rs` to preserve meaning of the test. - `rustfmt::skip` used in a few places where hand-formatting read more nicely: `enum/enum-match.rs` - Line number adjustments needed for the expected output of `debug-column.rs` and `coroutine-debug.rs`.

Stop using LLVM struct types for alloca The alloca type has no semantic meaning, only the size (and alignment, but we specify it explicitly) matter. Using `[N x i8]` is a more direct way to specify that we want `N` bytes, and avoids relying on LLVM's struct layout. It is likely that a future LLVM version will change to an untyped alloca representation. Split out from #121577. r? `@ghost`

fixes #99858

use [N x i8] for alloca types

2024-04-12T01:42:35+00:00

add tests for PassMode::Cast fixes

2024-03-17T04:39:21+00:00

Tests added in cast-target-abi.rs, covering the single element, array, and prefix cases in `CastTarget::llvm_type`, and the Rust-is-larger/smaller cases in the Rust<->ABI copying code. ffi-out-of-bounds-loads.rs was overhauled to be runnable on any platform. Its alignment also increases due to the removal of a `min` in the previous commit; this was probably an insufficient workaround for this issue or similar. The higher alignment is fine, since the alloca is actually aligned to 8 bytes, as the test checks now confirm.
